I wonder if anyone else has given this a try? I was diagnosed type 2 in July and have been taking 500mg 3 times a day. I have just had a hba1c result of 35. I have lost 2lbs in wt every week since diagnosis and now weigh only 9st 9lb. So I'm going to try a few days / weeks with no Metformin to see how it effects my bg readings and weight loss. I think my good hba1c result may be due to my low carb diet - we shall see!
